1. Ratings are at sea level to 2,000 feet. For altitudes above 2,000 feet, reduce all ratings 4% for each 1,000 feet above sea level.
2. Net steam ratings based on piping and pickup allowance of 1.333 (300-1600), 1.327 (1700), 1.319 (1800), 1.313 (1900),
1.307 (2000), 1.301 (2100), 1.296 (2200), 1.292 (2300), 1.290 (2400), and 1.288 (2500-3000). Contact Technical Support
before selecting boiler for installations having unusual piping and pick-up factors, such as intermittent system operations,
Supply and Return extensive piping systems, etc.
3. Ratings in square feet are computed at 240 Btuh/square foot for steam boilers.
